Marlin

Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. Many commercial 3D printers come with Marlin installed. Check with your vendor if you need source code for your specific machine. (by MarlinFirmware)

    There is _a lot_ wrong with Marlin. It is a complex codebase, full with ancient artefacts, litterred with preprocessor ifdefs every 2-3 lines of code, dynamic includes in the middle of CPP files, etc[1]. It's about as unreadable as C++ code gets--well, I guess it's not template metaprogramming.

    Klipper by contrast is a breeze to read through[2].

    I am very grateful for Marlin, for all of reprap, and everyone who has contributed to it. But saying there is nothing wrong with it is straight up misguided.

    I think you are mistaken. I can't speak for implementations preceding the Ender 3 V2, so what you're saying may have been true at some point for other machines. However, here you can see Marlin developers confirm that there is an EEPROM on the stock E2V2 board using diagrams from Creality and photographic confirmation. Here is the datasheet for the EEPROM. Here is a thread discussing this Marlin release, and also the then-recent release of official Creality firmware which resolved the same issue. Since the stock firmware is based on Marlin, and at the time Marlin did not support this type of EEPROM, the EEPROM was not usable at launch. Any mainstream firmware (official or third-party) from the last three years will be using the onboard EEPROM unless the user intentionally specified otherwise.

    As an example, check the macropocalypse in Marlin - but the actual trigger for me to start was Reprap firmware doing a floating point divide in interrupt context while targeting AVR8 core…

    Any change of thermistor or to a PT100/PT1000 will require recompiling the firmware, because every type has different characteristics. Marlin uses an internal table to calculate the temperature for whatever reading it gets from the CPU's analogue-to-digital converter. It has many tables for different thermistors, but only one is ever incorporated at compile time. So you have to specify which type you're using. You can see the commonly-used types in the list in Marlin's Configuration.h file, in the section headed // @section temperature. The tables themselves are in Marlin/src/module/thermistor.
